Hide editor field during registration but..

Keep the Pre-filled default value at registration only:

OK, So I created a field with skills, the registered users are not able to change it ( I used the privacy plugin for this. During registration the field is not visible

BUT,

after registration the pre-filled default value that I entered in the backend is gone from the registered user.

CB Version is 1.9.1

If I set User Read Only to NO and Show at Registration to Yes, the field show up, the data is in de database at the end of registration but during registration the fields are editable...

Please help
TIA

I still am struggling with this option.

I installed a component for frontend user creation but failed to get the default content of the field during this option.

Can anyone at least tell me if this is possible in 2.0? The website I'm using it fore is a Dutch site so I need to wait until the Dutch language file is complete.

Thanks for your help.
